I've seen plenty of UFC fights at the venue. They get better and better every time. The tickets are also cheaper than Mandalay Bay Events Center when they throw on fights.
The only reason I do not give this 5 stars is the Box Office's fault, not the venue's. I drove 6 hours from San Diego back in December last minute because I thought I snagged up some JayZ VIP tickets. My credit card was charged over a week before the show, yet my tickets were never in my name. Apparently I was charged for other tickets that were in someone else's name and this wasn't discovered by the box office or ticketmaster until I arrived. I was only granted a refund but it was too late for that. I'm already there for the concert and without tickets. Problem should've been fixed within 24 hours of my purchase not when I show up to see the show and get rejected. Biggest waste of my life driving all the way there for nothing because of someone else's mistake and failure to correct it. I still expect to be comped over this one day.
